In winter, a foraging flock might include several species of birds: chickadees, kinglets, and even a Downy Woodpecker. Many bird species eat alone, so you might wonder why these birds have chosen to dine together. Different species foraging in a group to find food enhances the success of all. One species assists the foraging of others. It's known as "commensal feeding." And more eyes and ears help protect the flock, too. Learn more at BirdNote.org.
